Definitions
- the present invention relates to a sterilizing cabinet assembly and a method for placing filters which makes use of such a sterilizing cabinet assembly.
- Sterilization is a term referring to any process that eliminates (removes) or kills microbial life, including transmissible agents (such as fungi, bacteria, viruses, or spore forms) present on a surface, or contained in a fluid, or in medication, or in a compound such as biological culture media. Sterilization can be achieved by applying heat, chemicals, irradiation, high pressure, and filtration or combinations thereof.
- surgical instruments and medications that enter an already aseptic part of the body must be sterilized to a high sterility assurance level.
- examples of such instruments include scalpels, hypodermic needles and implantable medical devices (IMD), such as artificial pacemakers.
- IMD implantable medical devices
- a widely used method for heat sterilization is the autoclave, sometimes referred to as a converter.
- Autoclaves commonly use steam heated to 121-134 °C.
- a holding time of at least 15 minutes at 121 °C at 100 kPA, or 3 minutes at 134 °C at 100 kPa is required.
- Additional sterilizing time is usually required for liquids and instruments packed in layers of cloth, as they may take longer to reach the required temperature.
- One method of sterilization involves passing steam through a cabinet.
- steam needs to penetrate the cabinet load uniformly. Accordingly, the cabinet must not be overcrowded, and the lids of bottles and containers must be left ajar. During the initial heating of the chamber, residual air must be removed. Indicators should be placed in the most difficult places for the steam to reach to ensure that steam actually penetrates there.
- a filter is typically placed over the vent to keep particles or extraneous materials from entering the cabinet before, during or after the sterilizing process. Once the sterilizing process is completed the filter needs to be removed and inspected by medical professionals to verify the integrity of the sterilizing process was maintained. If it is discovered during inspection that the filter did not remain intact, the sterilizing process has to be repeated with a new filter.
- CN 201 200 633 Y discloses a disinfecting storage cabinet capable of ventilation, which consists of a storage cabinet cabinet, a cabinet door, a diagonal filter tank, a sterilizing device, a wooden partition, a mesh filter hole, an electric air extractor and a microcomputer MCU control switch.
- a disinfecting storage cabinet capable of ventilation which consists of a storage cabinet cabinet, a cabinet door, a diagonal filter tank, a sterilizing device, a wooden partition, a mesh filter hole, an electric air extractor and a microcomputer MCU control switch.
- the timing control disinfection and ventilation switch on the microcomputer MCU switch is turned on, the disinfection device is activated, and the ozone sterilization device and the ultraviolet lamp sterilization device begin to work normally, after 10 to 20 minutes.
- US 8 454 901 B1 discloses a mobile apparatus and method to sterilize surgical trays.
- a cabinet has filtered cabinet roof vents, filtered cabinet floor vents, doors sealably covering a cabinet front aperture, shelves sized to support surgical trays, and wheels.
- Surgical trays are placed within the cabinet, the cabinet doors are closed, and the mobile apparatus is placed within an autoclave and sterilized.
- the cabinet doors are not unsealed until the cabinet is in the operating room, ready for use.
- doors are opened, trays removed, and their contents used.
- Wheels on the cabinet facilitate moving the cabinet from autoclave to storage or operating room. Method steps include periodically replacing the filters and door gasket.
- a first exemplary embodiment of the present invention provides a sterilizing cabinet assembly.
- the sterilizing cabinet assembly includes a cabinet having an access port and a door connected to the cabinet, the door moveable between an open position permitting passage through the access port to an interior of the cabinet and a closed position precluding passage through the access port.
- This embodiment further includes the door having a vent port and a primary filter overlying the vent port and forming a sealed interface with an adjacent portion of the one of the cabinet and the door.
- This embodiment further includes a secondary filter overlying at least a portion of the primary filter. In this embodiment, the secondary filter forms an independent sealed interface with the sterilizing cabinet or the primary filter.
- the method for placing filters according to the invention includes disposing a primary filter to occlude an access port of a sterilizing cabinet forming a first sealed interface with the sterilizing cabinet.
- the method further includes forming a second sealed interface between a confirmatory filter and at least a portion of one of the sterilizing cabinet and the primary filter, a portion of the confirmatory filter overlying a portion of the primary filter.
- the second sealed interface is independent of the first sealed interface.
- An example which is not part of the claimed invention, provides a sterilizing assembly which includes a sterilizing cabinet and a first tray and a second tray sized to be retained within the cabinet.
- the sterilizing assembly further includes at least one removable spacer intermediate the first tray and the second tray, the spacer being sterilizable and vertically separating the first tray and the second tray by a given height, the spacer inhibiting lateral displacement of the first tray relative to the second tray, wherein the given height is sufficient to permit a passage of a sufficient amount of a sterilizing agent between the first tray and the second tray for a predetermined time.
- a method of loading a sterilizing cabinet includes loading a sterilizable first pan and a sterilizable second pan within the sterilizing cabinet.
- the method further includes placing a removable and sterilizable spacer between the first pan and the second pan, the spacer (i) providing at least one of a predetermined vertical spacing between the first pan and the second pan and (ii) inhibiting horizontal displacement of the first pan relative to the second pan.
- a method of sterilizing includes loading a tray retaining a surgical instrument in a sterilization cabinet and sealing a primary filter relative to a vent port in the sterilization cabinet.
- the method further includes sealing a secondary filter relative to the vent port and independent of the sealed primary filter and passing a sterilizing agent through the secondary filter and the primary filter.
- a non-claimed sterilizable pan assembly includes a first sterilizable pan having an open top, a closed bottom and a pair of projecting spacer legs and a second sterilizable pan having an open top and closed bottom.
- the sterilizable pan assembly further includes the spacer legs configured to releasably engage a portion of the second pan and maintain a predetermined vertical spacing between the bottom of the first pan and the top of the second pan.
- a further non-claimed filtering assembly includes a primary filter holding portion for holding a primary filter for overlying a vent port and forming a sealed interface with a sterilizing cabinet.
- the filter assembly further includes a secondary filter holding portion for holding a secondary filter, moveably attached to the primary holding portion for overlying the primary filter holding portion and forming a sealed interface with the primary filter holding portion.
- a method for verifying sterilization includes performing a sterilization cycle in a sterilization device. The method further includes removing a secondary filter that is overlying a primary filter with a second sealed interface with the primary filter from the sterilizing device such that the primary filter maintains a sealed interface with a vent port of the sterilizing device and examining the secondary filter to verify the integrity of the sterilization cycle in the sterilizing device.
- a sterilizing cabinet assembly includes a cabinet having an access port and a door connected to the cabinet, the door moveable between an open position permitting passage through the access port to an interior of the cabinet and a closed position precluding passage through the access port.
- the sterilizing cabinet assembly further includes at least one of the cabinet and the door having a vent port and a filter overlying the vent port and forming a sealed interface with an adjacent portion of the one of the cabinet and the door.
- a further method of placing filters includes disposing a primary door to occlude an access port of a sterilizing cabinet, the primary door comprising an edge portion and an internal portion, the internal portion comprising a plurality of openings.
- the method further includes disposing a filter over the primary door to occlude the access port of the sterilizing cabinet and disposing a secondary door over the filter and the primary door, thereby forming a sealed interface with the filter, the primary door and the sterilizing cabinet.
- a method of verifying sterilization includes performing a sterilization cycle in a sterilizing device. The method further includes removing a secondary door that is overlying a filter with a second sealed interface with the filter from the sterilizing device.

- Exemplary embodiments of this disclosure provide for secondary filter 110 to form a sealed periphery with primary filter 108.
- the sealed interface between the primary filter 108 and the adjacent portion of either the sterilizing cabinet 100 is independent of an interface between secondary filter 110 and primary filter 108.
- One exemplary arrangement provides for primary filter 108 and secondary filter 110 to be coextensive.
- primary filter 108 and secondary filter 110 have different filter properties. For instance, primary filter 108 and secondary filter 110 may filter different elements of the sterilizing agent which exits sterilizing cabinet 100 during a sterilization cycle.
- primary filter 108 and secondary filter 110 have similar filter properties.
- Another exemplary embodiment provides that primary filter 108 and secondary filter 110 are different colors.
- primary filter 108 may be the only filter that covers vent 104.
- primary filter 108 is removeably held or maintained in place over vent 104 by filter holder 106.
- Primary filter 108 forms a seal with the adjacent portions of sterilizing cabinet 100 such that during the operation of a sterilizing cycle, any sterilizing steam that passes through the vent 104 must then pass through primary filter 108.
- primary filter 108 can be made of any porous material that (1) allows for the passage of sterilizing steam from sterilizing cabinet 100 and (2) prevents extraneous materials from passing through primary filter 108 and entering vent 104.
- Primary filter 108 is removable from sterilizing cabinet 100 and is typically replaced with a new filter following each sterilizing cycle.
- Legs 114 reside on the bottom of sterilizing cabinet 100 and provide spacing between the surface which sterilizing cabinet 100 rests and the bottom primary filter 108, secondary filter 110 and filter holder 106.
- Figure 1b provides a top view of sterilizing cabinet 100 showing vent 104 covered by filter holder 106, primary filter 108, secondary filter 110, sterilizing cabinet frame 112 and hinge 116 of filter holder 106.
- Hinge 116 with filter holder 106 allows a portion of filter holder 106 to swing open about hinge 116 such that primary filter 108 and secondary filter 110 can be removed independent of one another.
- filter holder 106 allows for secondary filter 110 to be released and removed from filter holder 106 while simultaneously maintaining primary filter's 108 seal with sterilizing cabinet 100 over vent 104.
- Figure 1c shows a side view of sterilizing cabinet 100 including sterilizing cabinet frame 112, vent 104, primary filter 108, secondary filter 110, filter holder 106 and hinge 116.
- sterilizing cabinet 100 may include a steam exposure indicator on either the primary filter 108 or the secondary filter 110 which designates when steam from sterilizing cabinet 100 has passed through one of the filters.
- An example of one such steam exposure indicator is a tape that changes colors when exposed to steam.
- Figure 2a provides a perspective view of sterilizing cabinet 100 with two vents 104 on the top and two vents 104 on the bottom of sterilizing cabinet 100.
- Figure 2a also includes primary filters 108 occluding vents 104 and secondary filters 110 overlaying primary filters 108 with primary filters 108 and secondary filters 110 each in filter holders 106.
- Figure 2b provides a top view of sterilizing cabinet 100 with an alternative exemplary embodiment of filter holder 106. Shown in Figure 2b are two vents 104 occluded by primary filters 108 which are also covered by secondary filters 110.
- filter holders 106 do not have a swinging hinge which allows for the individual attachment and release of primary filters 108 and secondary filters 110.
- filter holders 106 allow for independently removing primary filter 108 and secondary filter 110 through the use of a sliding mechanism. Secondary filter 110 can be removed by sliding it out of filter holder 106 while maintaining primary filter's 108 seal with sterilizing cabinet 100 around vent 104.
- filter holder 106 again does not include a swinging hinge, but allows for the placement and removal of only primary filter 108 by a sliding mechanism.
- Only primary filter 108 in conjunction with filter holder 106 forms a sealed interface with sterilizing cabinet 100 occluding vents 104. Primary filter 108 can then be placed or removed by sliding into and out of filter holder 106.
- an exemplary embodiment of a process of placing primary filter 108 and secondary filter 110 includes disposing primary filter 108 to occlude a vent 104 of sterilizing cabinet 100 and forming a first sealed interface with the sterilizing cabinet 100. The process continues by forming a second sealed interface between secondary filter 110 (or confirmatory filter) and at least a portion of one of sterilizing cabinet 100 and primary filter 108, a portion of the secondary filter 110 overlying a portion of the primary filter 108. The process can continue by passing a sterilizing agent (typically steam) through primary filter 108 and secondary filter 110 and vent 104.
- a sterilizing agent typically steam
- an exemplary embodiment of a process of placing only a primary filter 108 includes disposing primary filter 108 with filter holder 106 to occlude vent 104 of sterilizing cabinet 100 creating a sealed interface with the sterilizing cabinet 100.
- the process can continue by passing a sterilizing agent (typically steam) through primary filter 108 and vent 104.
- the process can then conclude with verifying the integrity of primary filter 108 by either inspecting primary filter 108 while it covers vent 104 in filter holder 106 or after it is removed from filter holder 106.
- the process may be repeated if it is determined that the integrity of primary filter 108 was compromised during the sterilizing process.
- Exemplary embodiments of inspecting primary filter 108 and/or secondary filter 110 can include visual inspection by either medical or non-medical personnel, inspecting by an electronic device or machine, or inspecting through mechanical means.
- Exemplary embodiments of inspecting by an electronic device or machine includes any type of device that is able to scan or image the primary filter 108 and/or secondary filter 110 such that the scanned or imaged picture of the primary filter 108 and/or secondary filter 110 can be digitally viewed or examined for imperfections such as rips or cuts that would impact the integrity of the sterilization cycle.
- Exemplary embodiments of mechanical inspection includes any type of inspection means that physically test that the integrity of the primary filter 108 and/or secondary filter 110 has been maintained.
- exemplary embodiments of a sterilizing agent include any substance that provides for the destruction or elimination of living organisms, which often include heat, steam, pressure, gas, plasma, irradiation, chemical compounds, and chemical vapor.
- Exemplary embodiments of this process provide that the first sealed interface is separate from the second sealed interface. Additionally, failure of the second sealed interface is independent of the first sealed interface. For example, if the second sealed interface fails and leaks sterilizing steam during a sterilization cycle, the first sealed interface should remain intact and should not be affected by the failure of the second sealed interface.
- FIG. 3a a top view of an exemplary vent 104 is shown.
- a fenestrated surface with numerous openings that allow for the passage of a sterilizing agent, such as steam from sterilizing cabinet 100 during a sterilization cycle.
- a sterilizing agent such as steam from sterilizing cabinet 100 during a sterilization cycle.
- Figure 3a merely represents one embodiment of vent 104 and that exemplary embodiments of vent 104 include any arrangement of holes or openings that allow for the passage of a sterilizing agent.
- Figure 3b provides a top view of a filtering arrangement covering vent 104. Shown in Figure 3b is the top portion of secondary filter 110, filter holder 106 with hinges 116 and pin 118. Exemplary embodiments of this arrangement provide for a silicon seal between filter holder 106 and primary filter 108, between filter holder 106 and secondary filter 110 and sterilizing cabinet 100. This seal serves two primary purposes. First, it forces all of the sterilizing agent that enters and exits the sterilizing cabinet 100 to pass through the filters. Second, it keeps extraneous materials from entering the sterilizing cabinet 100 through vents 104, which are covered by primary filter 108 and secondary filter 110.
- exemplary embodiments of the sealed interface between the primary filter 108 and the sterilizing cabinet 100 includes both direct contact between primary filter 108 and sterilizing cabinet 100 as well as indirect contact between primary filter 108 and sterilizing cabinet 100 through the use of a sealing agent, such as caulk or an adhesive.

- sections 402 and 404 are able to rotate about hinge 116 and can be moved from the closed position (covering vent 104) to the open position (not covering vent 104) independent of each other. For instance section 404 can be moved to the open position while section 402 remains in the closed position.
- section 404 in order for section 402 to move to the open position, section 404 must also be in the open position since it overlays section 402. Also shown in Figure 4a are holes 406 on section 402, section 404 and on sterilizing cabinet 100. When section 402 and 404 are in the closed position, the holes 406 line-up such that a pin 118 or locking key can be inserted through the holes 406. This prevents sections 402 and 404 from opening during a sterilization cycle or at any other time when opening would be undesirable.
- sections 402 and 404 are maintained or locked in the closed position through the use of a clamp or latch. It can be appreciated that exemplary embodiments of these teachings provide for any mechanism that allows sections 402 and 404 of filter holder 106 to be maintained securely in the closed position and then opened when desired.

Shown in Figure 4b is the outside face of sterilizing cabinet 100, vent 104, primary filter 108, hinge 116, and filter holder 106 section 402, which secures primary filter 108. It should be noted that in this exemplary embodiment, there is only one filter (i.e., primary filter 108) and one filter holder 106 section 402. Here, filter holder 106 section 402 is able to rotate about hinge 116. It can be moved from the closed position (covering vent 104) to the open position (not covering vent 104). Also shown in Figure 4b are holes 406 on section 402. When section 402 is in the closed position, the holes 406 line-up such that a pin 118 or locking key can be inserted through the holes 406. This prevents section 402 from opening during a sterilization cycle or at any other time when opening would be undesirable.
- section 402 is maintained or locked in the closed position through the use of a clamp or latch. It can be appreciated that exemplary embodiments of these teachings provide for any mechanism that allows section 402 of filter holder 106 to be maintained securely in the closed position and then opened when desired

This allows for secondary filter 110 to be removed from filter holder 106 while maintaining the position and seal of primary filter 108 over vent 104.
- Figure 6a provides a perspective view of an alternative sterilizing cabinet 100. Shown in figure 6a is sterilizing cabinet frame 112, bars 602 and hooks 604. In this embodiment there is no front side of sterilizing cabinet 100 in front of bars 602. It should be appreciated that exemplary embodiments of sterilizing cabinet 100 also include embodiments of sterilizing cabinet 100 that do not contain bars 602. In yet another exemplary embodiment of sterilizing cabinet 100, bars 602 are removeable such that bars 602 can be removeably affixed to sterilizing cabinet 100 when desired.
- Figure 6b illustrates filter door 606 which contains primary filter 106. In exemplary embodiments filter door 606 covers the front opening of sterilizing cabinet 100 in Figure 6a . Filter door 606 clamps onto sterilizing cabinet 100 with clamps 608. Bars 602 prevent the contents of sterilizing cabinet 100 (typically a tray containing instruments for sterilization) from ripping or breaking primary filter 108 and secondary filter 110.
- Figure 6c illustrates filter door 610 which attaches to filter door 606 and sterilizing cabinet 100 with the use of clamps 608.
- clamps 608 on filter door 610 fit into the spacing between clamps 608 on filter door 606. This arrangement prevents the clamps 608 from filter door 606 from interfering with clamps 608 from filter door 610.
- secondary filter 110 can be removed with filter door 610 after a sterilization cycle has completed without disturbing filter door's 606 seal with sterilizing cabinet 100.
- filter door 606 forms a seal with sterilizing cabinet 100 at the edges of the open portion of the sterilizing cabinet frame 112, such that any sterilizing steam that enters or exits sterilizing cabinet 100 during a sterilization cycle must pass through filter door 606 and primary filter 106.
- filter door 610 forms a seal with filter door 606 such that any sterilizing steam that exits sterilizing cabinet 100 and primary filter 108 must pass through filter door 610 and secondary filter 110.

- Primary filter 108 is placed on top of filter door 606 and attaches to sterilizing cabinet 100 at hooks 604. In this embodiment, there is only a single filter and no secondary filter.
- Primary filter 108 creates a sealed interface with filter door 606 such that extraneous materials cannot enter sterilizing cabinet 100.
- Filter door 610 is then placed on top of primary filter 108 and attached to sterilizing cabinet 100 with clamps 608.
- primary filter 108 does not create a sealed interface with filter door 606 until filter door 610 is placed on top of primary filter 108 and filter door 606.
- a sealed interface between filter door 610 and primary filter 108, and a sealed interface between filter door 606 or sterilizing cabinet 100 and primary filter 108 is only created when filter door 610 is attached or affixed to sterilizing cabinet 100.
- exemplary embodiments of filter doors 606 and 608 which contain numerous holes or openings along their surface, which allow for the passage of sterilizing steam.
- exemplary embodiments of Figure 7b provide that filter door 610 can be removed from sterilizing cabinet 100, primary filter 108 and filter door 606 without disturbing or disrupting the sealed interface between primary filter 108 and filter door 606. This will prevent the possibility of extraneous materials from entering sterilizing cabinet 100 after a sterilizing cycle when filter door 610 is removed in order to either allow primary filter 108 and filter door 606 to be removed as well or for primary filter 108 to be inspected to verify that it maintained its integrity during the sterilizing cycle.
- the sealed interface between filter door 610 and primary filter 108, and the sealed interface between filter door 606 or sterilizing cabinet 100 and primary filter 108 is broken or can be broken when filter door 610 is removed from sterilizing cabinet 100, primary filter 108, and filter door 606.
- the sealed interface between filter door 610 and primary filter 108, and the sealed interface between filter door 606 or sterilizing cabinet 100 and primary filter 108 is only created and thereafter maintained when sterilizing cabinet 100 along with filter door 610, filter door 606 and primary filter 108 are exposed to a sterilization cycle.

- spacer 802 for use in exemplary embodiments of sterilizing cabinet 100.
- spacer 802 has a wire frame and is sized such that when it is placed inside sterilizing cabinet 100 it does not move.
- the length and width of spacer 802 closely matches the dimensions (i.e., the depth and width) of the inside of sterilizing cabinet 100. This prevents spacer 802 from sliding or moving inside sterilizing cabinet 100 during a sterilization cycle or while sterilizing cabinet 100 is being moved.
- spacer 802 is shaped such that there are dividers or lips 804 along the edges of spacer 802 and at spacer's 802 midsection.
- the dividers or lips 804 are illustrated most clearly in Figures 8b and 8c .
- sterilizing trays can be placed on top of spacer 802 prior to a sterilization cycle.

- the length and width of spacer 902 closely matches the dimensions (i.e., the depth and width) of the inside of sterilizing cabinet 100. This prevents spacer 902 from sliding or moving inside sterilizing cabinet 100 during a sterilization cycle or while sterilizing cabinet 100 is being moved.
- Spacer 902 is shaped such that there are dividers or lips 904 along the edges of spacer 902 and throughout spacer's 902 mid-section.
- the dividers or lips 904 can be viewed most clearly in Figures 9b and 9c .
- sterilizing trays can be placed on top of spacer 902 prior to a sterilization cycle.
- the dividers or lips 904 provide a physical barrier between sterilizing trays creating a minimum separation between the trays. This allows the passage sterilizing steam during a sterilization cycle throughout sterilizing cabinet 100.
- Holes 906 encompasses any variation of openings that allow for the passage of sterilizing steam during a sterilization cycle yet maintaining structural integrity of spacer 902 to carry the weight of the sterilizing trays and their contents.
- spacers 802 and 902 provide for the spacer to be fenestrated. In another exemplary embodiment spacers 802 and 902 are not reusable but are disposable and can only be sterilized once. In another exemplary embodiment spacers 802 and 902 provide vertical spacing between trays by at least 0.1 to 5 inches. In yet another exemplary embodiment, spacers 802 and 902 provide vertical spacing between trays by at least 10 to 26 inches.

- the terms tray and pan are interchangeable and refer to an instrument with a closed rigid bottom and sides and an open top.
- Illustrated in Figure 10 is sterilizing tray 1000 with an open top and a closed rigid bottom and sides.
- Sterilizing tray 1000 can be made of any material that can be sterilized (sterilizable) and is rigid enough such that it can hold items to be sterilized.
- sterilizing tray 1000 can be made of metals or metal alloys.
- Exemplary embodiments of sterilizing tray 1000 provide for a tray that has dimensions that make it suitable for use with spacers 802 and 902 and sterilizing cabinet 100.

- the one or more sterilizing trays 1000 are of the shape and size so that they can be retained within sterilizing cabinet 100 and fit between the dividers 904 in spacers 902.
- a first tray is placed in sterilizing cabinet 100 on a spacer 902.
- spacer 902 is then placed.
- a second tray 1000 is placed in sterilizing cabinet 100 on top of spacer 902.
- the spacer 902 vertically separates the first tray 1000 from the second tray 1000 in sterilizing cabinet 100.
- Spacer 902 also inhibits lateral displacement of the first and second tray 1000 through the use of the dividers and lips 904.
- the spacers 902 play the important role of allowing sterilizing steam to pass between the sterilizing trays 1000 during a sterilization cycle.
- Exemplary embodiments of spacers 902 provide space between the first and second tray 1000 by at least 10 to 26 inches.
- Exemplary embodiments of these teachings also provide for a sterilizable pan assembly for sterilization within sterilizing cabinet 100.
- the sterilizable pan assembly as shown in Figure 12 illustrates a first sterilizable pan 1202 with an open top and a closed bottom. Protruding from the top of the first sterilizable pan 1202 are four legs 1204. Exemplary embodiments of the first sterilizable pan 1202 also includes legs 1204 that protrude from the bottom of the first sterilizable pan 1202. These legs are configured to releaseably attach to a portion of a second sterilizable pan 1206. Legs 1204 when attached to the second sterilizable pan 1206 maintain a vertical spacing between the bottom of the first sterilizable pan 1202 and the top of the second sterilizable pan 1206. In one exemplary embodiment the vertical spacing is at least 0.1 to 5 inches.

Exemplary embodiments of this pan assembly are configured such that they can be used within sterilizing cabinet 100 during a sterilization cycle.
- Filter 1302 can be made of any type of porous paper or cellulose type material. In other embodiments, filter 1302 is made of polymeric substances, such as polypropylene. Filter 1302 is required to be both porous and dense enough to allow the passage of a sterilizing agent, such as steam, through its membrane, but also resilient enough to not rip or tear during a sterilizing cycle or during insertion/clamping into a filter holder.
- a sterilizing agent such as steam
- filter 1302 is both porous and less resilient such that filter 1302 can be ripped or torn during use in a sterilizing cycle or with filter holder 106.
- the beaded edge 1304 creates a raised portion along the edges of the filter 1302 as shown in Figure 13b . This enables filter 1302 to create a sealed interface when used with sterilizing cabinet 100 and filter holder 106 over vents 104.
- beaded edge 1304 is placed inside the edge of filter 1302 rather than on the edge of filter 1302 such that there is a space between the edge of filter 1302 and beaded edge 1304.
- Exemplary embodiments of filter 1302 provide for filter 1302 to have different densities along given cross-sections of the face of filter 1302. For instance, filter 1302 may have a higher density along its periphery and a lower density towards its center. Exemplary embodiments of filter 1302 also provide for filter 1302 to have different thicknesses throughout its cross-section. The different thicknesses of filter 1302 provide different lengths of travel for sterilizing agents, which pass through filter 1302.
- Exemplary embodiments of filter 1302 have a length and width that corresponds to the size of vents 104 of sterilizing cabinet 100 and filter holder 106. Additionally, the thickness of beaded edge 1304 corresponds to a size that is able to fit between sterilizing cabinet 100 and filter holder 106 or between the different sections of filter holder 106. The thickness of beaded edge 1304 is also such that the sealed interface between sterilizing cabinet 100 and filter holder 106 or between the different sections of filter holder 106 prevents extraneous materials from entering sterilizing cabinet 100 and forces all of the sterilizing agent that enters and exits sterilizing cabinet 100 to pass through filter 1302.
- the beaded edge 1304 can be made of a silicone based material or any other material that can create a sealed interface between sterilizing cabinet 100 or filter holder 106 and filter 1302.
- the beaded edge 1304 also is required to be able to withstand high temperatures in excess of 275 degrees without compromising its structural or chemical integrity.
- Exemplary embodiments of filter 1502 have a length and width that corresponds to the size of vents 104 of sterilizing cabinet 100 and filter holder 106.
- FIG 14a provides an alternative exemplary embodiment of a filter suitable for use in practicing exemplary embodiments of this disclosure.
- Filter 1402 can be made of any type of porous paper or cellulose type material.
- filter 1402 is made of polymeric substances, such as polypropylene.
- Filter 1402 is required to be porous enough to allow the passage of a sterilizing agent, such as steam through its membrane, but also resilient enough to not rip or tear during a sterilizing cycle or during insertion/clamping into a filter holder 106.
- filter 1402 is both porous and less resilient such that filter 1402 can be ripped or torn during use in a sterilizing cycle or with filter holder 106.
- the folded edge 1404 is created by the edges of filter 1402 folded onto itself thereby creating a thicker membrane along the edges of filter 1402 as shown in Figure 14b .
- the thicker membrane of folded edge 1404 provides for a better-sealed interface between sterilizing cabinet 100 and filter holder 106 as there is less likelihood that spaces can be created between filter 1402 and sterilizing cabinet 100 which would allow for the passage of sterilizing steam or extraneous materials.

Description
- The present invention relates to a sterilizing cabinet assembly and a method for placing filters which makes use of such a sterilizing cabinet assembly.
- Sterilization is a term referring to any process that eliminates (removes) or kills microbial life, including transmissible agents (such as fungi, bacteria, viruses, or spore forms) present on a surface, or contained in a fluid, or in medication, or in a compound such as biological culture media. Sterilization can be achieved by applying heat, chemicals, irradiation, high pressure, and filtration or combinations thereof.
- In general, surgical instruments and medications that enter an already aseptic part of the body (such as the bloodstream, or penetrating the skin) must be sterilized to a high sterility assurance level. Examples of such instruments include scalpels, hypodermic needles and implantable medical devices (IMD), such as artificial pacemakers.
- A widely used method for heat sterilization is the autoclave, sometimes referred to as a converter. Autoclaves commonly use steam heated to 121-134 °C. To achieve a degree of sterility, a holding time of at least 15 minutes at 121 °C at 100 kPA, or 3 minutes at 134 °C at 100 kPa is required. Additional sterilizing time is usually required for liquids and instruments packed in layers of cloth, as they may take longer to reach the required temperature.
- One method of sterilization involves passing steam through a cabinet. For effective sterilization, steam needs to penetrate the cabinet load uniformly. Accordingly, the cabinet must not be overcrowded, and the lids of bottles and containers must be left ajar. During the initial heating of the chamber, residual air must be removed. Indicators should be placed in the most difficult places for the steam to reach to ensure that steam actually penetrates there.
- A filter is typically placed over the vent to keep particles or extraneous materials from entering the cabinet before, during or after the sterilizing process. Once the sterilizing process is completed the filter needs to be removed and inspected by medical professionals to verify the integrity of the sterilizing process was maintained. If it is discovered during inspection that the filter did not remain intact, the sterilizing process has to be repeated with a new filter.

US 8 454 901 B1 discloses a mobile apparatus and method to sterilize surgical trays. A cabinet has filtered cabinet roof vents, filtered cabinet floor vents, doors sealably covering a cabinet front aperture, shelves sized to support surgical trays, and wheels. Surgical trays are placed within the cabinet, the cabinet doors are closed, and the mobile apparatus is placed within an autoclave and sterilized. The cabinet doors are not unsealed until the cabinet is in the operating room, ready for use. During use in the operating room, doors are opened, trays removed, and their contents used. Wheels on the cabinet facilitate moving the cabinet from autoclave to storage or operating room.

This drastically helps prevent the spread of infectious materials. In the marketplace, there are a wide variety of devices that provide for sterilization of medical instruments through the use of a sterilizing agent, such as steam. Instrument trays can be wrapped in a cloth or paper that acts as a filter, allowing the tray to be sterilized, then delivered to the operating room. Alternatively, a rigid container can contain the instrument tray. Typically, the device (e.g., a rigid container) contains a vent for venting the steam used to sterilize the contents of the device. A disposable filter usually covers these vents. The filters have two major purposes. First, they prevent extraneous materials from entering the sterilizing device during and after the sterilization cycle. Second, they allow sterilizing steam to enter and exit the sterilizing device.
- However, in order to check that the integrity of the sterilization cycle has been maintained a person (usually a medical technician) must verify that there are no holes or other types of rips in the filter. This is done by removing the filter from the sterilizing device and visually inspecting the filter. This creates an inherent time period wherein the sterilized instruments can be contaminated by extraneous materials that enter the sterilizing device through the now open and uncovered vents. An object of exemplary embodiments of this disclosure provide a solution to this problem.
- Referring to
Figure 1a , is a front view of sterilizingcabinet 100. It should be noted that embodiments of the present invention are not limited to the particular configuration of sterilizingcabinet 100. - The
term sterilizing cabinet 100 encompasses any device capable of sterilizing. The term also includes sterilizing cabinets for sterilizing medical instruments, surgical devices and the like. - Sterilizing
cabinet 100 includes door ordoors 102, vents 104,filter holder 106,primary filter 108,secondary filter 110, sterilizingcabinet frame 112 andlegs 114. Door ordoors 102 are able to open and close for access to the interior of sterilizingcabinet 100. Door ordoors 102 are physically connected to sterilizingcabinet frame 112. Door ordoors 102 can be attached through the use of a hinge or hinges which allows the doors to swing open. Alternatively, door ordoors 102 can be removable from sterilizingcabinet 100 through the use of clamps (not shown inFigure 1 ). It should be appreciated that exemplary embodiments of door ordoors 102 include any mechanism that allows for door ordoors 102 to move from an open position to a closed position to provide access to the interior of sterilizingcabinet 100. - Sterilizing
cabinet 100 in this embodiment provides for fourvents 104. However, it should be appreciated that exemplary embodiments of sterilizingcabinet 100 are not limited to four vents. Exemplary embodiments of sterilizingcabinet 100 can include one or more vents. Twovents 104 on the top of sterilizingcabinet 100 and twovents 104 on the bottom of sterilizingcabinet 100.Vents 104 provide numerous small openings for the passage of sterilizing steam. The small openings invents 104 can be holes or slits. Alternatively, vents 104 can be fenestrated. -
Primary filter 108 in conjunction withfilter holder 106 covers vent 104.Primary filter 108 withfilter holder 106 forms a seal with the adjacent portions of sterilizingcabinet 100 such that during the operation of a sterilizing cycle, any sterilizing steam that passes through thevent 104 must then pass throughprimary filter 108.Primary filter 108 can be made of a very thin paper. Exemplary embodiments provide thatprimary filter 108 can be made of any porous material that (1) allows for the passage of sterilizing steam from sterilizingcabinet 100 and (2) prevents extraneous materials from passing throughprimary filter 108 and enteringvent 104.Primary filter 108 is removable from sterilizingcabinet 100 and is typically replaced with a new filter following each sterilizing cycle. -
Secondary filter 110 resides on top ofprimary filter 108 infilter holder 106.Secondary filter 110 coversprimary filter 108 and forms a seal withprimary filter 108 throughfilter holder 106 such that any sterilizing steam that passes through thevent 104 must then pass throughprimary filter 108 andsecondary filter 110.Secondary filter 110 can be made of a very thin paper.Secondary filter 110 can be made of any porous material that (1) allows for the passage of sterilizing steam from sterilizingcabinet 100 andprimary filter 108 and (2) prevents extraneous materials from passing throughsecondary filter 108. - Exemplary embodiments of this disclosure provide for
secondary filter 110 to form a sealed periphery withprimary filter 108. In another exemplary embodiment the sealed interface between theprimary filter 108 and the adjacent portion of either the sterilizingcabinet 100 is independent of an interface betweensecondary filter 110 andprimary filter 108. One exemplary arrangement provides forprimary filter 108 andsecondary filter 110 to be coextensive. In another exemplary embodimentprimary filter 108 andsecondary filter 110 have different filter properties. For instance,primary filter 108 andsecondary filter 110 may filter different elements of the sterilizing agent which exits sterilizingcabinet 100 during a sterilization cycle. In an alternative exemplary embodimentprimary filter 108 andsecondary filter 110 have similar filter properties. Another exemplary embodiment provides thatprimary filter 108 andsecondary filter 110 are different colors. - In yet another exemplary embodiment,
primary filter 108 may be the only filter that coversvent 104. Here,primary filter 108 is removeably held or maintained in place overvent 104 byfilter holder 106. In this embodiment, there is no secondary filter.Primary filter 108 forms a seal with the adjacent portions of sterilizingcabinet 100 such that during the operation of a sterilizing cycle, any sterilizing steam that passes through thevent 104 must then pass throughprimary filter 108. Again, in this embodiment,primary filter 108 can be made of any porous material that (1) allows for the passage of sterilizing steam from sterilizingcabinet 100 and (2) prevents extraneous materials from passing throughprimary filter 108 and enteringvent 104.Primary filter 108 is removable from sterilizingcabinet 100 and is typically replaced with a new filter following each sterilizing cycle. -
Legs 114 reside on the bottom of sterilizingcabinet 100 and provide spacing between the surface which sterilizingcabinet 100 rests and the bottomprimary filter 108,secondary filter 110 andfilter holder 106. -
Figure 1b provides a top view of sterilizingcabinet 100 showingvent 104 covered byfilter holder 106,primary filter 108,secondary filter 110, sterilizingcabinet frame 112 and hinge 116 offilter holder 106.Hinge 116 withfilter holder 106 allows a portion offilter holder 106 to swing open abouthinge 116 such thatprimary filter 108 andsecondary filter 110 can be removed independent of one another. In other words,filter holder 106 allows forsecondary filter 110 to be released and removed fromfilter holder 106 while simultaneously maintaining primary filter's 108 seal with sterilizingcabinet 100 overvent 104. -
Figure 1c shows a side view of sterilizingcabinet 100 including sterilizingcabinet frame 112, vent 104,primary filter 108,secondary filter 110,filter holder 106 and hinge 116. - In exemplary
embodiments sterilizing cabinet 100 may include a steam exposure indicator on either theprimary filter 108 or thesecondary filter 110 which designates when steam from sterilizingcabinet 100 has passed through one of the filters. An example of one such steam exposure indicator is a tape that changes colors when exposed to steam. -
Figure 2a provides a perspective view of sterilizingcabinet 100 with twovents 104 on the top and twovents 104 on the bottom of sterilizingcabinet 100.Figure 2a also includesprimary filters 108 occludingvents 104 andsecondary filters 110 overlayingprimary filters 108 withprimary filters 108 andsecondary filters 110 each infilter holders 106. -
Figure 2b provides a top view of sterilizingcabinet 100 with an alternative exemplary embodiment offilter holder 106. Shown inFigure 2b are twovents 104 occluded byprimary filters 108 which are also covered bysecondary filters 110. In this exemplaryembodiment filter holders 106 do not have a swinging hinge which allows for the individual attachment and release ofprimary filters 108 andsecondary filters 110. In this exemplaryembodiment filter holders 106 allow for independently removingprimary filter 108 andsecondary filter 110 through the use of a sliding mechanism.Secondary filter 110 can be removed by sliding it out offilter holder 106 while maintaining primary filter's 108 seal with sterilizingcabinet 100 aroundvent 104. - In another alternative exemplary embodiment,
filter holder 106 again does not include a swinging hinge, but allows for the placement and removal of onlyprimary filter 108 by a sliding mechanism. In this embodiment, there is nosecondary filter 110. Onlyprimary filter 108 in conjunction withfilter holder 106 forms a sealed interface with sterilizingcabinet 100 occluding vents 104.Primary filter 108 can then be placed or removed by sliding into and out offilter holder 106. - In practice, an exemplary embodiment of a process of placing
primary filter 108 andsecondary filter 110 includes disposingprimary filter 108 to occlude avent 104 of sterilizingcabinet 100 and forming a first sealed interface with the sterilizingcabinet 100. The process continues by forming a second sealed interface between secondary filter 110 (or confirmatory filter) and at least a portion of one of sterilizingcabinet 100 andprimary filter 108, a portion of thesecondary filter 110 overlying a portion of theprimary filter 108. The process can continue by passing a sterilizing agent (typically steam) throughprimary filter 108 andsecondary filter 110 and vent 104. - Also in practice, an exemplary embodiment of a process of placing only a
primary filter 108 includes disposingprimary filter 108 withfilter holder 106 to occludevent 104 of sterilizingcabinet 100 creating a sealed interface with the sterilizingcabinet 100. The process can continue by passing a sterilizing agent (typically steam) throughprimary filter 108 and vent 104. The process can then conclude with verifying the integrity ofprimary filter 108 by either inspectingprimary filter 108 while it coversvent 104 infilter holder 106 or after it is removed fromfilter holder 106. The process may be repeated if it is determined that the integrity ofprimary filter 108 was compromised during the sterilizing process. - Exemplary embodiments of inspecting
primary filter 108 and/orsecondary filter 110 can include visual inspection by either medical or non-medical personnel, inspecting by an electronic device or machine, or inspecting through mechanical means. Exemplary embodiments of inspecting by an electronic device or machine includes any type of device that is able to scan or image theprimary filter 108 and/orsecondary filter 110 such that the scanned or imaged picture of theprimary filter 108 and/orsecondary filter 110 can be digitally viewed or examined for imperfections such as rips or cuts that would impact the integrity of the sterilization cycle. Exemplary embodiments of mechanical inspection includes any type of inspection means that physically test that the integrity of theprimary filter 108 and/orsecondary filter 110 has been maintained. - It should be noted that exemplary embodiments of a sterilizing agent include any substance that provides for the destruction or elimination of living organisms, which often include heat, steam, pressure, gas, plasma, irradiation, chemical compounds, and chemical vapor.
- Exemplary embodiments of this process provide that the first sealed interface is separate from the second sealed interface. Additionally, failure of the second sealed interface is independent of the first sealed interface. For example, if the second sealed interface fails and leaks sterilizing steam during a sterilization cycle, the first sealed interface should remain intact and should not be affected by the failure of the second sealed interface.
- Referring to
Figure 3a , a top view of anexemplary vent 104 is shown. Provided is a fenestrated surface with numerous openings that allow for the passage of a sterilizing agent, such as steam from sterilizingcabinet 100 during a sterilization cycle. It can be appreciated thatFigure 3a merely represents one embodiment ofvent 104 and that exemplary embodiments ofvent 104 include any arrangement of holes or openings that allow for the passage of a sterilizing agent. -
Figure 3b provides a top view of a filteringarrangement covering vent 104. Shown inFigure 3b is the top portion ofsecondary filter 110,filter holder 106 withhinges 116 andpin 118. Exemplary embodiments of this arrangement provide for a silicon seal betweenfilter holder 106 andprimary filter 108, betweenfilter holder 106 andsecondary filter 110 and sterilizingcabinet 100. This seal serves two primary purposes. First, it forces all of the sterilizing agent that enters and exits the sterilizingcabinet 100 to pass through the filters. Second, it keeps extraneous materials from entering the sterilizingcabinet 100 throughvents 104, which are covered byprimary filter 108 andsecondary filter 110. - It can be appreciated that exemplary embodiments of the sealed interface between the
primary filter 108 and the sterilizingcabinet 100 includes both direct contact betweenprimary filter 108 and sterilizingcabinet 100 as well as indirect contact betweenprimary filter 108 and sterilizingcabinet 100 through the use of a sealing agent, such as caulk or an adhesive. Likewise, the sealed interface between the secondary filter and theprimary filter 108 orfilter holder 106 includes both direct contact betweenprimary filter 108 orfilter holder 106 as well as indirect contact through the use of a sealing agent, such as caulk or an adhesive. - Referring to
Figure 4a , provided is a side view of the different elements and the type of movement allowed forfilter holder 106 in exemplary embodiments of this invention. Shown inFigure 4a is the outside face of sterilizingcabinet 100, vent 104,primary filter 108,secondary filter 110, hinge 116,filter holder 106section 402 which securesprimary filter 108, and filterholder 106section 404 which securessecondary filter 110. In thisexemplary embodiment sections hinge 116 and can be moved from the closed position (covering vent 104) to the open position (not covering vent 104) independent of each other. Forinstance section 404 can be moved to the open position whilesection 402 remains in the closed position. However, in order forsection 402 to move to the open position,section 404 must also be in the open position since it overlayssection 402. Also shown inFigure 4a areholes 406 onsection 402,section 404 and on sterilizingcabinet 100. Whensection holes 406 line-up such that apin 118 or locking key can be inserted through theholes 406. This preventssections - In alternative
exemplary embodiments sections sections filter holder 106 to be maintained securely in the closed position and then opened when desired. -
Figure 4b provides a perspective view of the movement of an alternative filter arrangement of a sterilizing cabinet for use in practicing exemplary embodiments of this invention. Shown inFigure 4b is the outside face of sterilizingcabinet 100, vent 104,primary filter 108, hinge 116, and filterholder 106section 402, which securesprimary filter 108. It should be noted that in this exemplary embodiment, there is only one filter (i.e., primary filter 108) and onefilter holder 106section 402. Here,filter holder 106section 402 is able to rotate abouthinge 116. It can be moved from the closed position (covering vent 104) to the open position (not covering vent 104). Also shown inFigure 4b areholes 406 onsection 402. Whensection 402 is in the closed position, theholes 406 line-up such that apin 118 or locking key can be inserted through theholes 406. This preventssection 402 from opening during a sterilization cycle or at any other time when opening would be undesirable. - In alternative exemplary embodiments,
section 402 is maintained or locked in the closed position through the use of a clamp or latch. It can be appreciated that exemplary embodiments of these teachings provide for any mechanism that allowssection 402 offilter holder 106 to be maintained securely in the closed position and then opened when desired -
Figure 5a provides a perspective view of an alternative arrangement of sterilizingcabinet 100 withvents 104 on the sides of the cabinet. In thisembodiment filter holders 110 are located on the sides of sterilizingcabinet 100 withprimary filter 108 andsecondary filter 110. Also shown inFigure 5a arehangers 502 from which filterholder 106,primary filter 108 andsecondary filter 110 attach to sterilizingcabinet 100. It can be appreciated that exemplary embodiments of sterilizingcabinet 100 includevents 104,primary filter 108,secondary filter 110 andfilter holder 106 on the side of sterilizingcabinet 100. -
Figure 5b shows a front facing view ofvent 104 withfilter holder 106 overlayingvent 104 on sterilizingcabinet 100. In thisembodiment filter holder 106 is sized such its edges completely cover theportions surrounding vent 104.Figure 5c showsprimary filter 108 andfilter holder 106 overlayingvent 104.Primary filter 108 as shown hangs fromhangers 502 and attaches to filterholder 106 byclamps 504. -
Figure 5d showssecondary filter 110 infilter holder 106 overlayingprimary filter 108 and vent 104. In this embodiment the portion offilter holder 106 which holdssecondary filter 110 can be opened and closed through the use of hingedgasket 504 oncepin 118 is removed fromhole 406 maintaining the portion offilter holder 106 that holdssecondary filter 110. This allows forsecondary filter 110 to be removed fromfilter holder 106 while maintaining the position and seal ofprimary filter 108 overvent 104. -
Figure 6a provides a perspective view of analternative sterilizing cabinet 100. Shown infigure 6a is sterilizingcabinet frame 112,bars 602 and hooks 604. In this embodiment there is no front side of sterilizingcabinet 100 in front ofbars 602. It should be appreciated that exemplary embodiments of sterilizingcabinet 100 also include embodiments of sterilizingcabinet 100 that do not contain bars 602. In yet another exemplary embodiment of sterilizingcabinet 100,bars 602 are removeable such thatbars 602 can be removeably affixed to sterilizingcabinet 100 when desired.Figure 6b illustratesfilter door 606 which containsprimary filter 106. In exemplary embodiments filterdoor 606 covers the front opening of sterilizingcabinet 100 inFigure 6a .Filter door 606 clamps onto sterilizingcabinet 100 withclamps 608.Bars 602 prevent the contents of sterilizing cabinet 100 (typically a tray containing instruments for sterilization) from ripping or breakingprimary filter 108 andsecondary filter 110. -
Figure 6c illustratesfilter door 610 which attaches to filterdoor 606 and sterilizingcabinet 100 with the use ofclamps 608. In this embodiment it can be appreciated that clamps 608 onfilter door 610 fit into the spacing betweenclamps 608 onfilter door 606. This arrangement prevents theclamps 608 fromfilter door 606 from interfering withclamps 608 fromfilter door 610. Additionally, sincefilter door 610 is attached independently fromfilter door 606,secondary filter 110 can be removed withfilter door 610 after a sterilization cycle has completed without disturbing filter door's 606 seal with sterilizingcabinet 100. In thisembodiment filter door 606 forms a seal with sterilizingcabinet 100 at the edges of the open portion of the sterilizingcabinet frame 112, such that any sterilizing steam that enters orexits sterilizing cabinet 100 during a sterilization cycle must pass throughfilter door 606 andprimary filter 106. Likewise,filter door 610 forms a seal withfilter door 606 such that any sterilizing steam that exits sterilizingcabinet 100 andprimary filter 108 must pass throughfilter door 610 andsecondary filter 110. -

As shownfilter door 606 withclamps 608 attach around the frame of sterilizingcabinet 100.Primary filter 108 is placed on top offilter door 606 and attaches to sterilizingcabinet 100 athooks 604. In this embodiment, there is only a single filter and no secondary filter.Primary filter 108 creates a sealed interface withfilter door 606 such that extraneous materials cannot enter sterilizingcabinet 100.Filter door 610 is then placed on top ofprimary filter 108 and attached to sterilizingcabinet 100 withclamps 608. In another exemplary embodiment,primary filter 108 does not create a sealed interface withfilter door 606 untilfilter door 610 is placed on top ofprimary filter 108 andfilter door 606. In this embodiment, a sealed interface betweenfilter door 610 andprimary filter 108, and a sealed interface betweenfilter door 606 or sterilizingcabinet 100 andprimary filter 108 is only created whenfilter door 610 is attached or affixed to sterilizingcabinet 100. As illustrated inFigure 7b , exemplary embodiments offilter doors - It should be noted that exemplary embodiments of
Figure 7b provide thatfilter door 610 can be removed from sterilizingcabinet 100,primary filter 108 andfilter door 606 without disturbing or disrupting the sealed interface betweenprimary filter 108 andfilter door 606. This will prevent the possibility of extraneous materials from entering sterilizingcabinet 100 after a sterilizing cycle whenfilter door 610 is removed in order to either allowprimary filter 108 andfilter door 606 to be removed as well or forprimary filter 108 to be inspected to verify that it maintained its integrity during the sterilizing cycle. - In an alternative exemplary embodiment, the sealed interface between
filter door 610 andprimary filter 108, and the sealed interface betweenfilter door 606 or sterilizingcabinet 100 andprimary filter 108 is broken or can be broken whenfilter door 610 is removed from sterilizingcabinet 100,primary filter 108, and filterdoor 606. In yet another exemplary embodiment, the sealed interface betweenfilter door 610 andprimary filter 108, and the sealed interface betweenfilter door 606 or sterilizingcabinet 100 andprimary filter 108 is only created and thereafter maintained when sterilizingcabinet 100 along withfilter door 610,filter door 606 andprimary filter 108 are exposed to a sterilization cycle. Exemplary embodiments of sterilizingcabinet 100 as depicted inFIG. 7b are able to maintain the sealed interface betweenfilter door 610 andprimary filter 108, and the sealed interface betweenfilter door 606 or sterilizingcabinet 100 andprimary filter 108 for an extended period of time following being exposed to a sterilization cycle, such as sterilizing steam. For example, the sealed interface may be able to remain intact for as long as 30-90 days. In other exemplary embodiments the sealed interface may only remain intact for a matter of hours. - Referring to
Figures 8a, 8b and8c , provided are different views of aspacer 802 for use in exemplary embodiments of sterilizingcabinet 100. In thisembodiment spacer 802 has a wire frame and is sized such that when it is placed inside sterilizingcabinet 100 it does not move. The length and width ofspacer 802 closely matches the dimensions (i.e., the depth and width) of the inside of sterilizingcabinet 100. This prevents spacer 802 from sliding or moving inside sterilizingcabinet 100 during a sterilization cycle or while sterilizingcabinet 100 is being moved. It should be appreciated thatspacer 802 is shaped such that there are dividers orlips 804 along the edges ofspacer 802 and at spacer's 802 midsection. The dividers orlips 804 are illustrated most clearly inFigures 8b and8c . In practice, sterilizing trays can be placed on top ofspacer 802 prior to a sterilization cycle. In order to ensure that all of the contents of sterilizingcabinet 100 are sterilized, it is advantageous to prevent sterilizing trays from touching. This can obscure portions of the sterilizing trays or their contents from the sterilizing steam. As such, the dividers orlips 804 provide a physical barrier between sterilizing trays creating a minimum separation between the trays. This allows the passage sterilizing steam during a sterilization cycle throughout sterilizingcabinet 100. Additionally, the dividers orlips 804 ofspacer 802 are sized such that they accommodate the shape and size of sterilizing trays and thus substantially prevent lateral movement (e.g., sliding) of sterilizing trays when not desired before, during or following a sterilization cycle. -
Figures 9a ,9b and 9c illustrate analternative spacer 902 for use inside exemplary embodiments of sterilizingcabinet 100. In thisembodiment spacer 902 is made of thin sheets (e.g., metal or aluminum alloys) withholes 906 throughout the length of the sheets. In thisembodiment spacer 902 is sized such that when it is placed inside sterilizingcabinet 100 it does not move. The length and width ofspacer 902 closely matches the dimensions (i.e., the depth and width) of the inside of sterilizingcabinet 100. This prevents spacer 902 from sliding or moving inside sterilizingcabinet 100 during a sterilization cycle or while sterilizingcabinet 100 is being moved.Spacer 902 is shaped such that there are dividers orlips 904 along the edges ofspacer 902 and throughout spacer's 902 mid-section. The dividers orlips 904 can be viewed most clearly inFigures 9b and 9c . In practice, sterilizing trays can be placed on top ofspacer 902 prior to a sterilization cycle. In order to ensure that all of the contents of sterilizingcabinet 100 are sterilized, it is advantageous to prevent sterilizing trays from touching. This can obscure portions of the sterilizing trays or their contents from the sterilizing steam. As such, the dividers orlips 904 provide a physical barrier between sterilizing trays creating a minimum separation between the trays. This allows the passage sterilizing steam during a sterilization cycle throughout sterilizingcabinet 100.Holes 906 encompasses any variation of openings that allow for the passage of sterilizing steam during a sterilization cycle yet maintaining structural integrity ofspacer 902 to carry the weight of the sterilizing trays and their contents. - Exemplary embodiments of

In this embodiment the one ormore sterilizing trays 1000 are of the shape and size so that they can be retained within sterilizingcabinet 100 and fit between thedividers 904 inspacers 902. - In practice, as shown in
Figure 11 , a first tray is placed in sterilizingcabinet 100 on aspacer 902. On top of thefirst tray 1000spacer 902 is then placed. Next, asecond tray 1000 is placed in sterilizingcabinet 100 on top ofspacer 902. Thespacer 902 vertically separates thefirst tray 1000 from thesecond tray 1000 in sterilizingcabinet 100.Spacer 902 also inhibits lateral displacement of the first andsecond tray 1000 through the use of the dividers andlips 904. Thespacers 902 play the important role of allowing sterilizing steam to pass between the sterilizingtrays 1000 during a sterilization cycle. It can be appreciated that exemplary embodiments include the addition ofmore sterilizing trays 1000 andspacers 902 arranged in accordance with the first and second sterilizing trays described. Exemplary embodiments ofspacers 902 provide space between the first andsecond tray 1000 by at least 10 to 26 inches. - Exemplary embodiments of these teachings also provide for a sterilizable pan assembly for sterilization within sterilizing
cabinet 100. The sterilizable pan assembly as shown inFigure 12 illustrates afirst sterilizable pan 1202 with an open top and a closed bottom.

Exemplary embodiments of thefirst sterilizable pan 1202 also includeslegs 1204 that protrude from the bottom of thefirst sterilizable pan 1202. These legs are configured to releaseably attach to a portion of asecond sterilizable pan 1206.Legs 1204 when attached to thesecond sterilizable pan 1206 maintain a vertical spacing between the bottom of thefirst sterilizable pan 1202 and the top of thesecond sterilizable pan 1206. In one exemplary embodiment the vertical spacing is at least 0.1 to 5 inches. In another exemplary embodiment, the vertical spacing is such that it allows for the passage of a sterilizing steam from a sterilization cycle of sterilizingcabinet 100. Exemplary embodiments of this pan assembly are configured such that they can be used within sterilizingcabinet 100 during a sterilization cycle. - Referring to
Figure 13 a , provided is an exemplary embodiment of a filter suitable for use in practicing exemplary embodiments of this disclosure. Shown inFigure 13a isfilter 1302 with abeaded edge 1304.Filter 1302 can be made of any type of porous paper or cellulose type material. In other embodiments,filter 1302 is made of polymeric substances, such as polypropylene.Filter 1302 is required to be both porous and dense enough to allow the passage of a sterilizing agent, such as steam, through its membrane, but also resilient enough to not rip or tear during a sterilizing cycle or during insertion/clamping into a filter holder. In another embodiment,filter 1302 is both porous and less resilient such thatfilter 1302 can be ripped or torn during use in a sterilizing cycle or withfilter holder 106. Thebeaded edge 1304 creates a raised portion along the edges of thefilter 1302 as shown inFigure 13b . This enablesfilter 1302 to create a sealed interface when used with sterilizingcabinet 100 andfilter holder 106 overvents 104. In an alternative embodiment, beadededge 1304 is placed inside the edge offilter 1302 rather than on the edge offilter 1302 such that there is a space between the edge offilter 1302 and beadededge 1304. - Exemplary embodiments of
filter 1302 provide forfilter 1302 to have different densities along given cross-sections of the face offilter 1302. For instance,filter 1302 may have a higher density along its periphery and a lower density towards its center. Exemplary embodiments offilter 1302 also provide forfilter 1302 to have different thicknesses throughout its cross-section. The different thicknesses offilter 1302 provide different lengths of travel for sterilizing agents, which pass throughfilter 1302. - Exemplary embodiments of
filter 1302 have a length and width that corresponds to the size ofvents 104 of sterilizingcabinet 100 andfilter holder 106. Additionally, the thickness ofbeaded edge 1304 corresponds to a size that is able to fit between sterilizingcabinet 100 andfilter holder 106 or between the different sections offilter holder 106. The thickness ofbeaded edge 1304 is also such that the sealed interface between sterilizingcabinet 100 andfilter holder 106 or between the different sections offilter holder 106 prevents extraneous materials from entering sterilizingcabinet 100 and forces all of the sterilizing agent that enters andexits sterilizing cabinet 100 to pass throughfilter 1302. - The
beaded edge 1304 can be made of a silicone based material or any other material that can create a sealed interface between sterilizingcabinet 100 orfilter holder 106 andfilter 1302. Thebeaded edge 1304 also is required to be able to withstand high temperatures in excess of 275 degrees without compromising its structural or chemical integrity. Exemplary embodiments offilter 1502 have a length and width that corresponds to the size ofvents 104 of sterilizingcabinet 100 andfilter holder 106. -

Shown inFigure 14a isfilter 1402 with foldededge 1404.Filter 1402 can be made of any type of porous paper or cellulose type material. In other embodiments filter 1402 is made of polymeric substances, such as polypropylene.Filter 1402 is required to be porous enough to allow the passage of a sterilizing agent, such as steam through its membrane, but also resilient enough to not rip or tear during a sterilizing cycle or during insertion/clamping into afilter holder 106. In anotherembodiment filter 1402 is both porous and less resilient such thatfilter 1402 can be ripped or torn during use in a sterilizing cycle or withfilter holder 106. - The folded
edge 1404 is created by the edges offilter 1402 folded onto itself thereby creating a thicker membrane along the edges offilter 1402 as shown inFigure 14b . The thicker membrane of foldededge 1404 provides for a better-sealed interface between sterilizingcabinet 100 andfilter holder 106 as there is less likelihood that spaces can be created betweenfilter 1402 and sterilizingcabinet 100 which would allow for the passage of sterilizing steam or extraneous materials. Exemplary embodiments offilter 1402 have a length and width that corresponds to the size ofvents 104 of sterilizingcabinet 100 andfilter holder 106. - Additionally, the thickness of folded
edge 1404 corresponds to a size that is able to fit between sterilizingcabinet 100 andfilter holder 106 or between the different sections offilter holder 106. The thickness ofedge 1404 is also such that the sealed interface between sterilizingcabinet 100 andfilter holder 106 or between the different sections offilter holder 106 prevents extraneous materials from entering sterilizingcabinet 100 and forces all of the sterilizing agent that enters andexits sterilizing cabinet 100 to pass throughfilter 1402. - Referring to
Figure 15a , provided is another exemplary embodiment of a filter suitable for use in exemplary embodiments of this disclosure. Shown inFigure 15a isfilter 1502,filter edge 1504 andfilter center 1506.Filter 1502 can be made of any type of porous paper or cellulose type material. In other embodiments filter 1502 is made of polymeric substances, such as polypropylene.Filter 1502 is required to be porous enough to allow the passage of a sterilizing agent, such as steam through its membrane, but also resilient enough to not rip or tear during a sterilizing cycle or during insertion/clamping into afilter holder 106. In anotherembodiment filter 1502 is both porous and less resilient such thatfilter 1502 can be ripped or torn during use in a sterilizing cycle or withfilter holder 106. -
Filter edge 1504 provides for a thicker portion offilter 1502 as shown inFigure 15b . The thickness offilter edge 1504 enablesfilter 1502 to make a better compressed sealed interface with sterilizingcabinet 100 andfilter holder 106. Exemplary embodiments offilter 1502 have a length and width that corresponds to the size ofvents 104 of sterilizingcabinet 100 andfilter holder 106. Additionally, the thickness ofedge 1504 corresponds to a size that is able to fit between sterilizingcabinet 100 andfilter holder 106 or between the different sections offilter holder 106. The thickness ofedge 1504 is also such that the sealed interface between sterilizingcabinet 100 andfilter holder 106 or between the different sections offilter holder 106 prevents extraneous materials from entering sterilizingcabinet 100 and forces all of the sterilizing agent that exits sterilizingcabinet 100 to pass throughcenter 1506 offilter 1502. -
Center 1506 offilter 1502 includes all of the area offilter 1502 other thanedge 1504 that is of normal or customary thickness for a filter that allows the passage of sterilizing steam, but prevents the passage of other extraneous materials. - Shown in
